Patented July 24, 1934 UNITED STATES 1,967,686 HALIDE-MERCURI mTno-oREsoL's George W. Raiziss, Philadelphia, Pa., assignor to Abbott Laboratories, North Chicago, 111., a corporation of Illinois No Drawing. Application January 26, 1033, Serial No. 653,670

4 Claims. (01. 260-13) My invention relates to pharmaceuticals, and has to do more particularly with substances which are especially adapted for use as bactericides in the treatment of various infectious diseases of the human organism.

I have made the discovery that the halidemercuri derivatives of nitro cresols possess great efiicacy in the treatment of infectious diseases and, furthermore, are soluble in organic solvents, such as alcohol, ether, acetone, etc., as well as in animal and vegetable oils and fats. This solubility in oleaginous substances makes such a product extremely useful as a pharmaceutical and easy to administer.

This application is in part a continuation 01' my co-pending application, Serial No. 442,460, filed April 7, 1930, which discloses various halide-mercuri derivatives of nitro-cresols together with methods of making the same, and particularly 2-chloro-mercuri-B-nitro-ortho cresol.

The following examples illustrate preferred embodiments of my invention:-

Example One hundred grams of anhydro-hydroxy-mercuri-l-nitro-ortho-cresol are dissolved in 4 liters of boiling distilled water with the aid of 55 cc. of 40 per cent sodium hydroxide solution. After cooling the clear solution, the chloro derivative is precipitated by the addition of hydrochloric acid, using Congo red test paper. The precipitate is filtered, washed with distilled water until free from chlorides, and dried. This product, chloro mercuri 1 hydroxy-3-nitro-6-methylbenzene may be represented:

CH: HgOl I have also produced the following isomeric compounds, varying the above-described procedure only to the extent that I use as a starting material the appropriate isomeric anhydro-hydroxy-mercuri-nitro-cresol: Chloro-mercuri-lhydroxy-2-nitro-6-methy1-benzene, which may be represented:

OH NO:

Chloro-mercuri-l -hydroxy-4 -nitro 5 methylbenzene, which may be represented:

HgCl

Chloro-mercuri-l-hydroxy-2-nitro-4- methyl benzene, which may be represented:

Chloro-mercuri-1-hydroxy-2-nitro-3- methyl benzene, which may be represented:

2. As a pharmaceutical, chloro-mercuri-l-hydroxy-3-nitro-6-methy1-benzene, which may be represented by the formula:

droxy-2-nitr0-6-methyl-benZene, which may be represented by the formula:

4. As a pharmaceutical, chlcromercuri-l-hydroxy-2-nitr0-4-methyl-benzene, which may be represented by the formula:
